Introduction to the essentials on Cybersecurity

In the modern digital environment, the role of cybersecurity is now greater than it was before. Our computers, laptops and other devices contain various private and secure personal data, such as medical and financial records. Cybercriminals view this data like sweet honey and strive to steal it using increasingly sophisticated means.

What is Cybersecurity?

Computer security, also known as Cybersecurity or information security defines the measures used to deter unauthorized access, use, disclosure, modification, destruction, or disruption of computers and computer networks. This is a complicated and forever changing field as cyber-criminals continuously come up with innovative methods of attack.

While computer hardware is secured in the same way that sensitive equipment such as lockers and doors are protected, critical information and system access and authorization, on the other hand, are protected through complex security tactics and practices.

Why is Cybersecurity Important?

As an individual 

People use computers in almost every aspect of their lives – from everyday communication and entertainment to banking and shopping. Computers or mobile devices are often used for storing sensitive personal information, including financial data, medical records and social media accounts.

Individuals face dire consequences from a cyber-attack. A cybercriminal may steal an identity in order to open new credit accounts, take loans, and commit other criminal activities. Health care providers maintain confidential patient’s’ medical records and any breach of these data may result in black mailing or other harmful activities. In addition, cyber-attacks can impair an individual’s ability to work and express themselves.

As an organisation

Computers and networks are the lifelines for every organization, whether small or large. Computers are utilized to keep track of inventory, fill customer orders, and save financial records in businesses. Computers are used by governments to provide services to citizens and keep vital data. Computers are used in teaching students as well as running the operations of educational institutions.

Organizations are therefore susceptible to cyber-attacks. Such can hinder activities, affect brand image, and be detrimental to financials. This may involve ransomware attacks that encrypt an organization’s data such that it remains hidden till the required ransom is settled. One method involves flooding an organization’s website or network with requests such that it is not available in the first place either for customers or for employees.

Two different types of cybersecurity threats

Phishing: Social engineering attack refers to phishing in which the attacker attempts to deceive you to reveal sensitive information like password and credit card numbers.

Malware: Malware is referred to as malicious software that has a capability of disrupting and damaging a computer system. It can also steal your data or allow other people to control your computer.

How to protect yourself from computer security threats   

• Always employ strong passwords and MFA
• Regularly update your software
• Take care while clicking on links and opening attachment.
• Install a firewall and antivirus.
• ensure knowledge about the latest tricks and attack paths.  

Benefits of having strong security and a secure firewall 

Protection Against Unauthorised Access: A firewall keeps possible attackers out of your network. It assists in guarding against unwanted access to your data and systems. Safeguarding confidential data and guaranteeing that only individuals with permission can access it are made possible by this protection.

Network Traffic Control: By using pre-established security rules, firewalls can be set up to regulate both incoming and outgoing network traffic. By using this feature, you can increase network security by filtering and blocking potentially dangerous content, such as malware, and limiting access to particular websites or services.

Increased Productivity: In a corporate environment, a firewall can increase worker productivity by screening and preventing access to websites and services that aren't connected to work. By ensuring that workers are concentrated on their work, it lessens interruptions.

In the current digital era, cybersecurity is a need rather than a luxury. It is impossible to overestimate the significance of protecting our digital assets, private data, and vital infrastructure as we traverse an increasingly interconnected world.

we've covered a range of cybersecurity topics, from comprehending the changing threat landscape to putting best practises into action to safeguard our businesses and ourselves. It is evident that there are significant risks involved, and that ignoring cybersecurity can have disastrous effects for people as well as society.
